Plot an Ragraph (using Rgraphviz)

Description

Usage

plotRag(ragr, sub, subArgs = .optRagargs(), ...)

Arguments

ragr an object of class Ragraph (as defined in the Rgraphviz package).
sub a “footnote” or subtitle to be added to plot(ragr,...). By default gives the number of nodes and edges.
subArgs ~~Describe subArgs here~~
... further arguments passed to plot(.), i.e., the plot method for Ragraph objects.

Examples

  if(require("Matrix")) {
    trMatrix <- classTree("Matrix")
    trMatrix
    RtrM <- mRagraph(trMatrix)
    RtrM # (the show method will hopefully improve)
    str(RtrM, max=2) # shows a bit more

    plot(RtrM) ## almost the same as
    plotRag(RtrM, subArgs=.optRagargs(adj = 0.5))
               ## which just gives "<n> nodes with <m> edges"
  }
